Our Families:
The Duke family DNA project is making possible the
identification of separate family groups bearing the surname ŅDukeÓ through
distinctive yDNA patterns. Families with similar and related surnames (Dukes,
Duc, Dugue, DuGu, or other variants) are also included in this surname group.
The study also allows us to clarify the internal histories of these family
groups.
The Duke surname DNA study is being
conducted by Family Tree DNA, with analysis of samples at the University
of Arizona.
Several major Duke family groups
have been identified:
- Group 1: One individual is
definitely a descendant of Joseph Duke of Orangeburg County, SC, and
documents indicate that the other test subject is a descendant of Joseph
or a close relative of his. Joseph Duke appears in the Orangeburg parish
records in 1750. SNP subclade testing has placed this family in haplogroup
J2a4b* (previously known as J2f, J2a1a in the Sengupta et al 2006 nomenclature, or J2a2),
which probably arose from a mutation in the vicinity of the Caucasus and
spread through maritime contact with areas on the coasts of Crete, western
Anatolia, Italy, and Spain.
More Information is available at
the Group
1 Web site.
- Group 2: This large family
includes descendants of 17th century Isle of Wight Co VA settler John
Duke. Their haplogroup is I, the second most common among persons of
European descent.
More
Information is available at Group 2 Web Site.
- Group 3: Another group of three tested
individuals is associated with the family of Mordecai Duke. This family group
falls within haplogroup I.
- Group 4: This group includes individuals from
eastern Henrico County, VA, from Kentucky via Maryland, from North
Carolina, Georgia, and Mississippi. Many individuals are believed to be
descendants of Capt. Henry Duke of Prince George Co. VA, through his son
John Taylor Duke. Three test subjects are from the Henrico Co VA area; one
of these test subjects is from a line that includes a
Mastin/Maston/Marston Duke in Henrico Co, VA, a name that is documented in
the family of Col. Henry Duke. The group also includes three descendants
of Squire Staggs Ashley from Orange County, NC, believed to be a Duke
descendant who took the Ashley name. The Group 4 haplogroup is R1b1b2*.
- Group 5: This group includes several families
that emigrated from the South Carolina Midlands (Fairfield, Kershaw,
Richland and Lexington counties) to Alabama and Mississippi. It also
includes the family of John Duke of Lancaster Co SC, whose sons John and
Moses Duke went on to Barnwell Co SC, John later immigrating to Tatnall Co
GA. This group falls within haplogroup R1b.
More Information is available at Group 5 web site.
- Group 6: A single individual represents a Duke
family in Maryland, believed descended from Ark and Dove
colonist Richard Duke. The haplogroup is R1b.
- Group 7: The one individual in this group
represents a family from Dorset, England. The haplogroup is N, common
among Uralic speakers of northern Eurasia.
- Group 8: This group is associated with Stephen
Duke of Lancaster Co, SC, and Robert Duke of Dry Creek, Lancaster County,
SC. Their haplogroup is I1.
- Group 9:This individual is descended from James
Green Duke of Orange, Caswell, and Rockingham County, NC. His haplogroup
is R1b.
- Group 10: This individual is descended from
William and Mary Duke of MD, through their son Richard who married
Elizabeth McDougle on 14 Nov 1799 in Culpepper VA. She died Ohio, and
their son William married Rebecca Rowland there. His haplogroup is R1b.
- Group 11: This individual is descended from T.
J. Duke of Belfast, Ireland. SNP testing has placed this group in
haplogroup T (previously K2), an old lineage found in low frequencies in
Africa, Asia and the Middle East, also the haplogroup of the family of
Thomas Jefferson. The specific haplotype of the individual in this group
is found at low frequency in southern Europe, northern Africa, and the
Middle East.
More
information is available the Group 11 Web Site.
- Group 12: This individual is descended from a
family traced to 1830 in Morgan Co., GA. His haplogroup is R1b.
- Group 13: This individual is descended from a
family traced to Monroe and Belmont Co. Ohio in the 19th
century.
- Group 14: This individual is haplogroup R1a,
and is descended from Jan Duke of Dobrzankowo, Poland.
- Group 15: A single individual in haplogroup
R1b1c6, from Ireland.
- Group 16: A single individual of unknown
origin, haplogroup E1b1b1.

haplogroup Q.
- Group 18: Duke family of Williamsburg County,

- Group 23: Meredith Duke of Fairfield County,
SC, GA and AL
- Group 24: adopted individual; mother a Duke,
father her third cousin
- Group 25: lineage documented in ChesterÕs Gap,
VA
- Group 26: SC and Muscogee County, GA.
Individuals in this group match some individuals in Group 4, but do not
match the modal values for that group. Any relationship to members of that
group appears to be ancient and predates the period for which genealogical
data are available. It is also
possible that some members of this group do not have a common ancestor
with others in the group within recent centuries.

1770 in Louisa (?) Co., VA, d. 1839 in Barren Co., KY

Note for Oxford Ancestors Customers: As you can see, we make our results freely available for
comparative purposes, to help not only our own members but
anyone researching the Duke surname. Unfortunately, Oxford Ancestors charges
£50 for access to their database and they provide no information on the size of
the database or information available, so we havenÕt taken that approach. Since
you are here using our data, you obviously believe in free access, and we hope
that you will let us know if you match any of our groups. Thank you! Lynn
